Hello,
Refering to the attached schematic, my purpose is to make a buffer for the TCXO. I'm using this TCXO, and AD8062 for the op amp.
A few details:
1. The op amp was at first biased using a 3V single supply.
2. The TCXO gives more or less clean 16MHz pulses ranging from 0V to 1.3V.
However, the output of the voltage follower was really distorted.
Then I've decided to bias the op amp using a dual supply voltage. Now, the output waveform was much cleaner but still not distortion free (especially on the falling edge of the signal there is an overshoot below zero).
My question are:
1. What else can I do to reduce the distortions ?
2. What should I have done to make it work using a single power supply?
Thanks for the help,
Alex
